Description of the BWS Extension 4-piece insert set:

With this BWS Extension, you can quickly convert the standard 18mm milling template into one suitable for fire-resistant rebates up to 27mm.

Fit the BWS Extension plate, which has pre-drilled screw holes, onto any router bit you wish to use for a fire-resistant rebate and secure it with the screws provided. Once you have mounted the BWS Extension onto the relevant router bit, mill the pattern of the router bit from the BWS Extension (using the standard 24mm copying ring and 18mm router bit, of course). Then drill the guide holes with a 6mm drill bit and the BWS Extension is ready for use.

Component features:

• Supplied with all fixings
• suitable for any router template
